fix(e2e): update chunks synchronously in store to prevent rechunk timeout

ChunkPanel emitted 'rechunked' which triggered an async re-fetch via
analysisStore.select() — but Vue does not await async emit handlers,
so chunk-cards never appeared before the E2E 30s timeout.

Now rechunk/edit/delete write returned chunks directly into the
analysis store via updateChunks(), removing the async round-trip.
